I build lights

[ttystikk]

@Zaphod420 this is designed to give great bloom light at 30" over a 2x3' spot. 37.5W/ft², 225W at the wall, driver and all. Cree 3590 3500 Kelvin. 120 degree glass lenses.

To cover larger areas, just mount more of these about 2' apart...

Nur muh gwad dude....

So about 1600W over roughly 5'x6' or 30ft² = 53W/ft²? You must be running that beast over a bigger footprint than the light itself?

I ran it last run as you see it, wall to wall, wasn’t a good led conversion run, blasting it didn’t work lol. I will try it out again in a different room, bigger, doing another HID run right away in the meantime.

So it sounds like there isn't any dimming capability? It is indeed possible to build a light with too much output. I was concerned enough about not getting things just right to build my lights as individual modules that I could then mount with different spacing to address this issue.

Since each bar has its own driver it looks like you could easily spread them apart further to get the same effect.

Water cooled?

Yeah they have a 1-10v dimmer, was too lazy to dimmer pot them all together, ran it prob 25% for the last month. Had a reveg event, light related somehow. I built the light to run at a high fixed position and to fit the room, I overkill most things. This current room is too small, I’m fixing up a 8x11 area to use that light in, prob a 6x6 footprint.

I could space the bars apart, it’s on steel L bracket like used in shelving, the strips are on aluminum, bolted to the steel, wiring it was brutal.

You were running 4 or 8 off of one HLG-185H-700B?
It's 143 to 286volts output. Does running 4 (without a dimming pot) give you 1400mA?

 

[NoWaistedSpace]

Couple I built recently.
I use COBs and 301H's with add UV,660,IR 3500K. 3 centers are the 660's


Bottom light, the ends slide out and you can drop or raise them or angle them.

Badass light.. Nice n clean !

Yep!

There were four 72V COBs, running at 54W.

Thanks man! I just use shit I have lying around for the hardware on my lights. I try and use 14-18ga "solid core" wire as much as possible. I use brass screw tube connectors. I don't care for the Wagos. Plastic snap touches one side of the wire.

I got ya, thought you had the 36 volt 3590's. I run Vero 29's, they are workhorses. I've never lost not one in going on 6 years running them.
But those damn Meanwells, I've lost 5 drivers in 6 years.
I like the 240-2100mA type A. I get over 300 watts out of each.
I like the 480-1400mA, they'll run 9 Veros 29's or 18 paired. 18 makes a nice spread.

Very nice! I'm looking to build a 240W light to cover a 2x4' space. I want to use strips, but it needs to be in the same efficiency class as quantum boards.

 

[NoWaistedSpace]

I ripped 3 x 360pc Atreum boards down the middle and mounted them on 2 x 6.08" heatsinks.
That's a 4' Pure UV sitting on top.
Running it on a 240-1400mA or 2 sets (4 bars) on a 480-1400mA.

I'm running 8 of Growdaddys strips on 1 240-2100mA. (4 pairs) About 306 watts at the wall. Around 35 watts each?
That's pretty efficient at 2.4 microjoules/sec

Is that a solarcure UV?

Agromax

Thanks I am firmly in the UV camp and use 4 ft tubes. I run mine for 3 hours then off for 2 and on for 3 more. Run mine for a year then change them out.

I'd like to push that up to 2.7 if I can without making it so expensive that it isn't worth it. That extra 10% makes a difference over time.
